Abstract
The present technique relates to a demodulation device, a demodulation method and a program capable of realizing a demodulation process at a rate equivalent to a case where I and Q channel signals are not inverted, even when the I and Q channel signals are inverted. A frequency correction unit establishes synchronization of a frequency and clock based on a signal from a frequency synchronization unit. A channel inversion detection unit of a frame synchronization unit detects presence or absence of inversion of I and Q channel signals, and supplies, as a detection result, a channel inversion detection result to the channel inversion control unit. The channel inversion control unit switches the I and Q channel signals if the inversion has occurred, based on the channel inversion detection result. This technique can be applied to a demodulation device.
